Abstract

In order to reduce spatial hole burning -SHB- that restricts the performances of DFB lasers, a AMC -amplitude modulated coupling- structure is introduced into MQW DFB -multiquantum well distributed feedback- lasers emitting near 1.55μm. The highest single longitudinal mode output power is 78mW at 500mA (cw operation). Modelisation of AMC structure behaviour above threshold is presented, and high power single mode oscillation of devices confirms that AMC flattens the power distribution along the cavity.
